Changelog

0.1.0 — Unreleased

first public release

tui login screen with username/password fields, session switcher, and status messages
supports x11, wayland, and tty sessions
pam authentication via cgo (thread-locked for safety)
faillock integration — detects lockouts, shows remaining attempts, admin bypass via ctrl+u
conway's game of life background rendered at 30 fps with unicode half-block characters
spring animation on switcher transitions
shake animation on failed login
caps lock indicator via ioctl
configurable power controls (shutdown/reboot on f1/f2 by default)
toml configuration with $VARIABLE substitution
preview mode (--preview) to test the login screen without leaving your session
utmpx user accounting (glibc only)
x11 session setup — xauthority cookies, sigusr1 handshake, server timeout
privilege dropping for child processes
log piping with 64 mb cap

utmpx time field portability — replaced hardcoded C.__uint32_t / C.__int32_t casts with a C helper function (auth/utmpx_time.h) that lets the compiler handle type conversion. fixes build failure on systems where ut_tv uses struct timeval instead of the 32/64 compat struct
makefile deps target — added make deps to automatically install libpam0g-dev and build-essential, and verify go is present
readme overhaul — rewrote for clarity: added "what problem does this solve", "how it works", known issues, simpler install instructions, and proper dependency listing

no tests
session spawning uses ForkExec which is less clean than the original fork-then-exec model
not all config options affect the rendering yet
occasional terminal state corruption on abrupt exit
automata background can flicker on rapid terminal resizes
